The EHC control unit is fully compatible with diagnostics.
The EHC control unit receives the following signals:
- Vehicle ride height
- Load cutout signals
- Terminal 15 ON/OFF
- Vehicle speed
- Lateral acceleration
- "Engine running" signal
- Hatch status.
The EHC control unit decides on a case-by case basis whether a control operation is required in order to compensate for changes in load.
It is thus possible to optimally adapt the frequency, specified heights, tolerance thresholds and battery load to the relevant situation by means of the control operation.
